A voltage of 1.2 V is dropped across an input pin when a 100-μA current is forced into the pin. Subsequently, a 1.254-V level occurs when the current is increased to 200 μA. What is the input resistance?
Design an analog Butterworth lowpass filter that has a 0.5 dB or better ripple at 10 kHzand at least 45 dB of attenuation at 20 kHz. Determine the system function in a cascade form.
In a long cilindric wire with a radius of 2 cm, a corrent with 80A goes thorugh it. What is the magnetic energy per unit of wire lenght?
An exponential waveform given by v (t) = 25 e-5000t u (t) V repeats every five time constants.- Find Vp, Vpp, VMAX, and VMIN.- Find Vavg and Vrms. - Find the period T0 of the waveform.
Consider a series RLC circuit disconnected from a source at t=0. The circuit components are R=3 ohms, C = 500 F, and L = 1 H. We assume that Vc(0-) = 20 V and i(0-) = -0A. a) Find the natural reponse i(t) for t > 0.
A magnetic flux of 400 microwebers passing through a coil of 1200 turns is reversed in 0.1 sec. Calculate the average value of the e.m.f induced in the coil.
What is a particle's speed if its kinetic energy T is equal to its rest energy?
Using the format approach, write the mesh equations for the networks of given figure. Is symmetry present?- Using determinants solve for the mesh currents.
The motor is synchronized to 22 kV mains. Calculate the maximum load on the motor (including rotational loss) before it could lose synchronism. What is the corresponding current and power factor?
Desired D.C. Output : 10 V Load Variation: 0.3 kilo-ohms - 10 kilo-ohms Ripple Factor: Less than 0.1% for 2 kilo-ohms load Load Regulation: Better than 3 mV for a 1 mA change in load current
The couple M acts in a vertical plane and is applied to a beam oriented as shown.
What are Active, Reactive, Apparent and Complex Power. ?? (include explanation with formuls )
If the collector of a transistor is connected to the base terminal, the transistor continues to operate in the forward-active mode, since the B-C junction is not reverse biased biased. Determine the small-signal resistance, re=Vce/Ie
